Recently the Cemu developers implemented a feature in the latest (experimental) Cemu builds to combine and compress Wii U games + their updates and DLC into a single file with a .wua (Wii U Archive) extension. This file format can be run directly from your Wii U roms folder and updates and DLC no longer have to be installed into Cemu 's virtual file system. Not only does this save some space, but managing your Wii U games becomes a lot easier with a single file per game instead of thousands in a folder structure. Coincidentally this makes importing your Wii U games into LaunchBox a lot easier too. No longer do you need to manually add the game 's executable (.rpx) to LaunchBox or use a LaunchBox Wii U importer plugin as importing single file games is as easy as it gets. Before you start, backup your current Cemu install. When combining and compressing your games into single files your old games won't be deleted. So you can experiment and delete them afterwards. - Download the latest Cemu build here. I started with a fresh install. - Open Cemu and point Cemu to your Wii U games folder. - Go to Tools --> Title Manager. Then sort by Type --> base. - Right click your game --> Convert to compressed Wii U archive .wua As I did a fresh Cemu install, after compressing my games into single files, I copied Cemu's controllerProfiles / gameProfiles / sdcard / shaderCache folders from my old Cemu folder into my new Cemu folder. Then I copied my old savegame folder (cemu\mlc01\usr\save) to the correct folder in my new Cemu install. Of course you don't need to start with a new Cemu install, but remember, with the new file format you don't need to install game updates and DLC's into Cemu's virtual file system. So you can remove (please backup) the cemu\mlc01\usr\title folder. With the 22 Wii U games that I have, that saved 22 GB of space in the Cemu folder alone. In LaunchBox you can edit your Wii U games to point to the newly created .wua files or just re-import your Wii U games folder. Maybe check if your emulator paths are still correct in the LaunchBox emulator settings. Lastly a rediit thread with some additional info.

Full sets take up a lot of space. I have that space, but that doesn't mean I want to use any more than I have to. Additionally, importing folders full of bin/cue/wav/etc for certain disc rips is messy. In a perfect world, every game would be compressed and stored in a single file. It seems most systems have at least one option, but with so many emulators and so many compression formats, it's been tricky figuring out what that option is. So far I've determined the following system - emulator - compression combos: PSP - PPSSPP - CSO Playstation 1 - Beetle PSX - CHD Playstation 2 - PCSX2 - GZ Gamecube/Wii - Dolphin - GCZ Dreamcast - DEmul - CHD Are these the best combos for these systems? What about other disc-based systems - Amiga CD32, Sega CD, etc? Thanks.

Hi all, I am wondering which are the best emulators for both Xbox classic and 360 right now even if they are in development. What I am aware at the moment is there is Cxbx and Xenia for each console. Appart from this, is there any way these emus (or other you may know) can open other compressed game extensions? I am squeezing my hard drive at the moment. Thanks a lot and have a good weekend

so I'm trying to save space and compress my roms and then let Launchbox extract them as needed, this works GREAT for PS1 and earlier generation ROMs because they are already relatively small files. But when I tried this on my PS2 games it works, but takes forever (which is understandable sine the file I tested was a Double Layered Disc that is 8 GB), so my question is, which compression settings are the best for not only saving on File Size, but also Fast Extraction Time? For the record I am using 7zip and compressing to .ZIPs with these settings: Ultra, LZMA, 8 MB, 128 Word Size. These settings brought my 8 GB ROM down to 6.8 GB, so its a decent amount of savings. What settings have you guys tried and what do you think would work the best?

Hi all, As I stated yesterday, I am new around and planning to get a massive game collection (with time and effort). Even though, I have realised -talking of CD games era- that they take a lot of storage so, trying to figure this out before getting a proper external storage, I would like to know which is the best way to store games to have an idea of how much room I can have occupied in a hard drive. I am thinking of PS1, PS2, PSP, Game Cube, DreamCast, Wii and Xbox Classic for now. I am asking this because most of them seem to be in RAR and then some bin+cue inside or an iso file or something similar. Is there any compressed way launchbox emulators can read them so I can save as much storage as possible? Many thanks.

so I finally got around to dealing with my video files here's how you can compress your video files with no loss of quality. http://blogs.it.ox.ac.uk/adamweblearn/2013/10/how-to-compress-large-video-files-without-losing-quality-using-handbrake/ the program is free, super easy to use.
